AD5521JST Precision Parametric Measurement Unit (PMU) from Analog Devices Inc.

The AD5521JST is a high-performance Precision Parametric Measurement Unit (PMU) designed by Analog Devices Inc., a leader in high-performance analog, mixed-signal, and digital signal processing integrated circuits. This advanced component is engineered to meet the rigorous demands of parametric measurement in test equipment, automatic test equipment (ATE) systems, and precision measurement applications.

The AD5521JST offers a wide range of features that make it an ideal choice for applications requiring precise voltage and current sourcing and measurement. It is capable of sourcing voltage from -10V to +10V and current from -20mA to +20mA, with excellent accuracy and stability. This flexibility allows for a broad range of testing capabilities, from simple go/no-go tests to complex characterization tasks.

One of the key attributes of the AD5521JST is its integrated 18-bit digital-to-analog converter (DAC), which ensures fine resolution and precise control over the output signals. The DAC's high resolution is complemented by a low glitch energy, minimizing the impact on the device under test and improving measurement integrity. Additionally, the PMU incorporates a 16-bit analog-to-digital converter (ADC) for accurate measurement of the sourced or sinked current and voltage.

The device also features an on-chip programmable gain amplifier (PGA) for current measurement, which allows for a wide dynamic range and improved sensitivity for low-level measurements. The PGA can be configured to multiple gain settings, providing the flexibility to adjust the measurement range as per the application requirements.

Designed with ease of integration in mind, the AD5521JST comes in a compact LQFP surface mount package that is suitable for space-constrained applications. It also includes a serial interface for communication with microprocessors or DSPs, enabling straightforward integration into a system's digital control loop.

Overall, the AD5521JST from Analog Devices Inc. stands out for its precision, versatility, and integration features, making it a top choice for engineers and designers in need of a reliable PMU for their high-precision measurement systems.
